16° on Nov. 14, 2014, the coldest reading for this week of the year since 1980. Next is 19° in 1985.
Willapa’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 520 ft, a difference of 520 ft: hilly country. The highest named summit within 15 miles is Walville Peak, about 2,460 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Alluvium (silt, sand), from the Holocene, less than 12,000 years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, siltstone. Age: Miocene, 5.3 to 23 million years old. About 8 mi of the line.
Basalt. Age: Early Paleocene to Middle Eocene, 40 to 64 million years old. About 5 mi of the line.
Sandstone, conglomerate, conglomerate-sandstone. Age: Late Eocene to Miocene, 5.3 to 38 million years old. About 4 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sandstone. Age: Early Eocene to Middle Eocene, 38 to 56 million years old. About 3 mi of the line.
Sandstone, siltstone. Age: Middle Eocene to Early Miocene, 16 to 48 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Willapa reaches the Pacific Ocean by way of Whitcomb Creek, Ward Creek and the Willapa: about 16 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Willapa; river miles along the main stem, rounded.
Willapa has a warm-summer Mediterranean climate. Summer afternoons average 73° in August; winter nights fall to about 32° in February. About 84 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Willapa normally reaches 52° and falls to 35°. The record high is 61°, in 2021; the record low 16°, in 2014. The most rain on this date, 2.72 in, fell in 2001.
Normals 1991–2020 and records since 1980 at Raymond 2 S, 3 miles west-southwest. NOAA, through RCC-ACIS.
